Project Name   
GSP Widening, Milepost 88.5 to 93.5

Project Description

We are providing engineering design and the development of contract drawings, specifications and cost estimates for the replacement of four (4) bridges and eight (8) Sign Structures, as part of the New Jersey Turnpike Authority’s Garden State Parkway (GSP) Mainline Widening for Shoulder Restoration Program from Milepost 88.5 to 93.5.  

SJH is responsible for the phased design of four bridges carrying GSP over Chambers Bridge Road and Route 88.  We are currently working on the development of Phase C plans. Two bridges involve superstructure replacement with semi integral abutments, and two are completely new structures. The existing structures are single span multi steel stringer concrete deck bridges.  They will be replaced with similar longer and wider single span bridges.  The use of semi integral abutments with wrap around MSE walls along with other structural configurations, such as the use of prestressed concrete beams, was investigated during the Pre Phase B Structure Type Study.  Seismic analysis will be performed.  The reconstruction is staged and three lanes of traffic on GSP in each direction are maintained at all times.  This is achieved by the use of “crossover” lanes.

We are also responsible for developing design drawings and details for Sign Structures.
